Awetted-wall absorption tower is fed with water as the wall liquid and an ammonia-air gas mixture as the central-core gas. at a particular level in the tower, the ammonia concentration in the bulk gas is 80 mol%, that in the bulk liquid 5 mol%. the temperature is 30 c and the pressure 1 atm. the local mass transfer in the liquid is kl = 2.87*10-5 m/s and in the gas is kc = 0.0362 m/s. calculate the local molar flux for the absorption of ammonia using the overall mass-transfer coefficient ky, ignoring the vaporization of water.

note: for this problem, use equilibrium data of nh3-water from appendix a.3-22 from the textbook.

Which step in naming unsaturated hydrocarbons is used for alkenes but not alkynes

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. one potential application of nanotechnology is the construction of artificial cells. the simplest cells would probably mimic red blood cells, the body's oxygen transporters. for example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. if the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. suppose that the nanocontainers were cubic and had an edge length of 24 nanometers. part a part complete what is the volume of one nanocontainer? (ignore the thickness of the nanocontainer's wall.) express your answer using two significant figures. v v = 1.4ă—10â’20 l previous answers correct significant figures feedback: your answer 1.3824â‹…10â’20 = 1.382ă—10â’20 l was either rounded differently or used a different number of significant figures than required for this part. if you need this result for any later calculation in this item, keep all the digits and round as the final step before submitting your answer. part b suppose that each nanocontainer could contain pure oxygen pressurized to a density of 81 g/l . how many grams of oxygen could be contained by each nanocontainer?

According to the kinetic-molecular theory, what happens to a liquid when it is transferred from one container to another? the volume and the shape stay the same. the volume increases to fill the new container, but the shape stays the same. the volume stays the same, but the shape changes to fit the new container. the volume and the shape change to fill the new container.
